內(nèi)容簡介

　　本書從數(shù)據(jù)通信的角度解釋和分析了計算機網(wǎng)絡(luò)中所涉及到的通信概念。與通常的計算機網(wǎng)絡(luò)教材不同之處在于作者是以通信系統(tǒng)的觀點對網(wǎng)絡(luò)的通信協(xié)議進行描述，主要講述了數(shù)據(jù)的通信過程和具體實現(xiàn)的方式。因此，對加強理解計算機網(wǎng)絡(luò)的原理有極大的幫助。本書前9章主要講述通信基礎(chǔ)。這就為非通信專業(yè)人員學(xué)習(xí)計算機網(wǎng)絡(luò)打下良好的基礎(chǔ)；后16章內(nèi)容涉及了計算機網(wǎng)絡(luò)的許多主要問題，其中包括：？OSI結(jié)構(gòu)，TCP/IP協(xié)議，ATM，Sone/SDH，F(xiàn)rame？Relay和局域網(wǎng)等；這對于學(xué)過或了解網(wǎng)絡(luò)的人員來講，有助于他們加強對網(wǎng)絡(luò)的理解。與第一版相比，本書增加了很多新的內(nèi)容如：IPv6，？56K調(diào)制解調(diào)器和電線調(diào)制解調(diào)器，傳輸損壞和傳輸媒體性能，交換以太網(wǎng)和千兆以太網(wǎng)，點對點協(xié)議，通信量控制，數(shù)字用戶線路（DSL）技術(shù)，光纖到路邊（FTTC）技術(shù)，交換式結(jié)構(gòu)和ATM？LANs，追加加密方法，Lempel-Ziv-Welch壓縮方法和生成樹算法。本書另外兩個特色是：書中的插圖生動形象，有助于對許多概念的理解；每章后的實踐環(huán)節(jié)能促進學(xué)員復(fù)習(xí)、鞏固和提高。此外教師和學(xué)生可以通過網(wǎng)址www.mhhe.com/forouzan查詢到補充資料。本書對于從事計算機網(wǎng)絡(luò)的工程技術(shù)人員。大學(xué)本科生、研究生來說都是一本很有價值的參考書。
